A straight prohexadione-calcium product

The only straight prohexadione-calcium product available in the UK, specifically developed for cereals.

This product can be co-applied in bespoke ratios with other PGRs, enabling applications to be tailored to both crop requirement and conditions of the season

  • Gram for gram, prohexadione is the most active PGR on the market
  • Provides activity across all major PGR timings
  • Excellent tank mix compatibility
  • Approved for use in Oats

Effective in a range of climatic conditions

  • prohexadione is active in temperature ranges of 8°– 20°, making it an ideal product for early timings
  • Unlike other PGRs which require conversion to the biologically active form within the plant prohexadione is already active by the time the applied spray has dried onto the crop foliage
Crop Safety Mixing Partners

Excellent crop safety

  • Safe to apply in a broad range of climatic conditions
  • Produces more uniform crop height without a ‘wave’ effect
  • Very kind to the crop unlike other PGR Materials

Mixing Partners

Chemically and Biologically – chlormequat is an excellent mixing partner for Prohex

Chlormequat chloride has a complimentary mode of action which supports prohexadione. Prohexadione-calcium is not active as a PGR – it requires conversion into the active prohexadione acid form. Chlormequat chloride acidifies the spray solution, aiding the conversion of prohexadione-calcium from the inactive calcium salt to the active acid form.
